How to resize the Photoshop interface?

The resolution of my monitor is 3440 * 1440 pixels.
At the same time, the Photoshop interface is very small, the tool icons are hard to see. 
I set the interface size to 200% in the settings but it doesn't help I can't see the size change.
What could be the problem is there any other settings for resizing the interface Photoshop version 2021

Hi

What operating system do you have

Not sure if you should adjust your monitor resolution to a lower resolution like 2560x1080...etc.

"I set the interface size to 200% in the settings"

With current Windows and Photoshop versions, you set the UI scaling in Windows Settings. Photoshop picks it up from there.

The PS preferences setting is for older Windows versions. It has no effect on current Windows versions.
